Is Xander's profile better at 2b or 3b? If Xander is a better fit at 3b, you need to move both players. I would hold off until there was a suitable SS replacement though (Mayer). Eventually, Devers would be LF/DH IMO.
Jeter: highest fWAR season was 2009 at 6.7
Xander: highest fWAR season was 2019 at 6.8
Therefore, Xander is as good as Jeter offensively BUT better than Jeter defensively by far.
I would get rid of either Vaz or Plawecki. Replace Vaz with Manny Pina or replace Plawecki with some cheap glove only guy who is just holding a spot for Hernandez or Wong.
I'd consider Arroyo to be the UTIL guy and sign Cesar Hernandez to play 2b.
Offer QO to ERod.
Sign Stroman.
